Air pollution is not the same everywhere. Different pollutants are released into
the atmosphere from a wide range of sources. Once in the atmosphere, they
can transform into new pollutants and spread around the world. Designing and
implementing policies to address this complexity are not easy tasks. Below is an
overview of air legislation in the European Union.

Emissions of air pollutants derive from almost all economic and societal activities. They result
in clear risks to human health and ecosystems. In Europe, policies and actions at all levels have
greatly reduced anthropogenic emissions and exposure but some air pollutants still harm human
health. Similarly, as emissions of acidifying pollutants have reduced, the situation for Europe's rivers
and lakes has improved but atmospheric nitrogen oversupply still threatens biodiversity in sensitive
terrestrial and water ecosystems. The movement of atmospheric pollution between continents
attracts increasing political attention. Greater international cooperation, also focusing on links
between climate and air pollution policies, is required more than ever to address air pollution.

The Thematic Strategy on air pollution aims to improve European air pollution significantly by 2020. This report from the European Environment Agency looks a further ten years into the future, and brings together two major policy challenges — combating climate change and reducing air pollution — in an integrated way. Thus, the report analyses projected changes in European air quality up to 2030, and explores the possible benefits of climate policies on air quality and the costs of air pollution abatement.

This report presents an overview and analysis of
air quality in Europe from 2002 to 2011. It reviews progress
towards meeting the requirements of the air quality
directives and gives an
overview of policies and measures introduced
at European level to improve air quality and
minimise impacts. An overview of the latest findings and
estimates of the effects of air pollution on health
and its impacts on ecosystems is also given.

The present report considers the status and trends of pan-European biodiversity, and the implications
of these trends for biodiversity management policy and practice. It considers the key biodiversity policy instruments currently applied in Europe, the threats to biodiversity and their management implications across major habitat types. The implications for biodiversity of cross-cutting issues such as tourism and urban planning are also considered, along with the challenges that remain for conserving and sustainably using of Europe's biodiversity. The report makes use of the SEBI 2010 indicators and other relevant national and regional information sources. It does not consider the biodiversity of EU overseas territories and outermost regions.
